Book of Books Jackpots
There is a decent maximum win of 10,000x your stake on the Book of Books slot. While the hit frequency is not reported, your best chance of hitting the biggest payouts comes from the extra spins in the bonus round. You’ll get potential for unlimited free spins, so while there is high volatility in the game, there is the potential for larger wins if you trigger the free spins.
Book of Books Slot Bonus Features
Power Up feature: The main modifier on the Book of Books slot game is Power Ups, which act as a boost for the free spins bonus. If you get 2 scatter symbols during a base game spin, you’ll get one of the following features for your extra spins:
- 1 or 2 extra free spins
- An extra expanding symbol
- 1x or 2x boosts that multiply wins on expanding symbols
Free Spins feature: Land three scatter symbols in the base game to trigger the free spins bonus round. The more scatters you get, the more paylines you open to create a new grid:
- 3 Scatters = 10 paylines and a 5×3 grid
- 4 Scatters = 20 paylines and a 5×4 grid
- 5 Scatters = 40 paylines and a 5×5 grid
You get 7 free spins by default, plus the extra free spins you have from the Power Ups during the base game. The additional expanding symbols provide bigger payouts by covering a whole reel when they land in a winning combination. Scatter symbols that appear during the free spins can re-trigger the bonus round, potentially up to an unlimited amount:
- 2 Scatters = 1 free spin and 1 random Power Up
- 3 Scatters = 3 free spins and 1 random Power Up
- 4 Scatters = 5 free spins, 1 random Power Up, and a 5×4 grid
- 5 Scatters = 7 free spins, 1 random Power Up, and a 5×5 grid
Remember that this is a high volatility slot, and there are no guarantees you will trigger the free spins or win any payout. Always play within your budget and remember to gamble responsibly. If you want to know more, our guide to safer gambling is a helpful resource.
Book of Books Slot Gameplay
Book of Books gameplay has a familiar five-reel Book slot setup, but it moves at a livelier pace than most slot games. The visuals and aesthetic are fantastic – symbols appear with bouncy animations and the on-screen characters strum, bang, and blow their instruments through every spin. The base game keeps things simple, while free spins create expanding symbols and more exaggerated effects. Even the music playing behind feels medieval’y.
Book of Books Slot Payouts
